Compare Medicare Plans in Missouri (July 2026)

Key Takeaways:

• Missouri offers its residents many Medicare options, including 134 Medicare Advantage plans and 16 stand-alone Part D plans.
• All Medicare beneficiaries in the state have access to at least one Medicare Advantage plan with zero monthly premiums.
• Finding the best Medicare plan involves evaluating your healthcare needs and the insurer's claims processing efficiency, among other factors.

Medicare is a complex health insurance program with multiple providers, coverage options, and cost-sharing components — and for eligible Missouri residents, that complexity can translate into real financial stakes.

Navigating the choices available in the Show-Me State means weighing a confusing array of plan types, carrier options, and coverage rules that directly affect both your healthcare and your budget. This guide breaks it all down.

Types of Medicare Plans Available in Missouri

Original Medicare (Part A and Part B)

Original Medicare is the cornerstone of federal health insurance for people aged 65 and above, as well as younger individuals with certain qualifying disabilities and diseases.

It has two components:

• Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care.

The Part A deductible in 2026 is $1,736. Coverage is premium-free for those who have paid Medicare taxes for at least 10 years; others pay $285 or $518 in monthly premiums depending on their work history.

• Part B (Medical Insurance): Covers outpatient care, doctor visits, preventive services, lab tests, and durable medical equipment.

In 2026, the annual deductible for Part B is $283, while the standard monthly premium is $202.90.

Despite the broad coverage Original Medicare provides, it doesn't pay for all healthcare-related costs. Beneficiaries remain liable for significant out-of-pocket expenses, including copayments and coinsurance. Under Part B, for example, you're responsible for 20% of the approved cost of a service or item once you've met the annual deductible — with no cap on how high those 20% amounts can climb.

Medicare Advantage (Part C)

Private insurers are free to add coverage options beyond Original Medicare's baseline — provided their plans still deliver all the benefits of Parts A and B. In practice, that means Missouri residents can find Medicare Advantage plans that bundle in prescription drug coverage, hearing, vision, dental, and even certain wellness programs, depending on the carrier and plan structure.

Here are some important facts about Medicare Advantage plans in Missouri:

• Average monthly premiums for Medicare Advantage plans rose from $10.19 to $12.69 in 2026.
• The state offers 134 Medicare Advantage plans in 2026, down slightly from 139 plans the prior year.
• Every Medicare enrollee in Missouri has access to at least one Medicare Advantage plan with a $0 monthly premium.

Medicare Prescription Drug Plans (Part D)

Part D can be purchased as a stand-alone plan alongside Original Medicare or come bundled as part of a Medicare Advantage plan.

There are two key factors to weigh when choosing a Part D plan:

Plan Formulary

A formulary is the list of drugs covered by a Part D plan. It's organized into different cost-sharing tiers — the tier your medication falls into directly determines what you pay out of pocket for it each month.

Pharmacy Networks

Each Part D plan works with a defined network of pharmacies, and filling prescriptions outside that network can be difficult or significantly more expensive. Confirm that your preferred pharmacies are in-network before selecting a plan.

Here are some key facts about Part D plans in Missouri in 2026:

• Missouri has 16 stand-alone Part D plans available in 2026, with all Medicare enrollees having access to at least one.
• 64.69% of people with Part D coverage can move to a plan with lower premiums than they paid the prior year.
• 23.09% of Part D enrollees in Missouri receive additional financial assistance through the federal Extra Help program.

The cost of a Part D plan depends on several factors, including the specific medications you require, where you live, and your income level.

Under the Inflation Reduction Act of 2022, out-of-pocket costs for covered drugs under Medicare Part D are now capped at $2,000 per year — a significant new protection for beneficiaries on high-cost medications.

Medicare Supplement (Medigap) Plans

Missouri offers 10 standardized Medigap plans — labeled A through N — with benefits that remain identical regardless of which insurer sells them. Where carriers differ is in their premiums, financial strength, and claims service.

Two of the most popular Medigap plans in Missouri are Plan G and Plan N. Here's how they compare:

• Plan G covers nearly all out-of-pocket costs under Original Medicare except the Part B deductible. The higher premium is offset by the predictability it delivers — you'll know your maximum exposure before you receive a single bill.

• Plan N carries relatively lower monthly premiums, but requires some cost-sharing on doctor visits and emergency room care. It doesn't cover the Part B deductible or excess charges, making it a better fit for budget-conscious enrollees who want meaningful protection without paying for every possible gap.

Medigap Plan G premiums in Missouri typically range from $237 to $409 per month, with your actual premium depending on factors like gender, location, and tobacco use. Plan N premiums generally range from $85 to $200 per month.

Top Medigap providers in Missouri include:

• Anthem Blue Cross Blue Shield
• Cigna
• Humana
• Aetna
• Mutual of Omaha

How to Choose the Right Medicare Plan in Missouri

The right Medicare plan starts with an honest assessment of your healthcare needs. Work through these considerations before comparing specific plans:

• How frequently do you need medical care? What type? Do you manage any chronic conditions or require specialized treatments?
• What ongoing treatments, planned procedures, or elective surgeries are on the horizon? Confirm they're covered under the plan you're considering.
• Are your preferred doctors, specialists, hospitals, and medical equipment suppliers in-network? This is often the most consequential factor for Medicare Advantage enrollees.

From there, move to a thorough review of costs and benefits:

• Compare plans based on total annual costs — not just monthly premiums. Factor in copayments, coinsurance, and any other out-of-pocket expenses.
• Assess your prescription drug needs carefully. Check how different Part D plans price your specific medications, both monthly and over the course of a year.
• Weigh the additional benefits different Medicare Advantage plans offer — dental, vision, hearing, fitness memberships — and determine which ones genuinely matter given your health and lifestyle.

How to Enroll in a Medicare Plan in Missouri

Missouri residents who have been receiving Social Security benefits for at least four months are automatically enrolled in Medicare Part A and Part B when they turn 65.

• Initial Enrollment Period (IEP): Begins three months before your 65th birthday, includes your birth month, and extends through the three following months — a total of seven months. During this window, you can enroll in Original Medicare (Part A and Part B), Medicare Advantage (Part C), and Part D prescription drug plans.

• Annual Enrollment Period (AEP): From October 15 to December 7 of each year, you can switch from Original Medicare to Medicare Advantage or vice versa, change Medicare Advantage plans, enroll in a Part D plan, or switch Part D plans.
• Medicare Advantage Open Enrollment Period (MA OEP): Runs from January 1 to March 31 each year. During this window, you can switch Medicare Advantage plans or return to Original Medicare.

• Special Enrollment Periods (SEPs): Certain life events — relocating to another state, losing employer coverage, or becoming eligible for Medicaid — can trigger a Special Enrollment Period, allowing you to make changes outside standard enrollment windows.

Steps to Enroll

Here's a step-by-step overview of the enrollment process:

1. Prepare Your Paperwork: Gather your Medicare card (if already enrolled), Social Security card, proof of citizenship or legal residency, a list of your current medications, and your current healthcare providers.
2. Decide How to Enroll: You have four options.

• • Online: Through the Social Security Administration or the Medicare websites.
  • By Phone: Call 1-800-MEDICARE (1-800-633-4227).
  • In Person: Visit your local SSA office. Find it through the SSA office locator.
  • Through an Agent: Licensed insurance agencies can offer personalized guidance and support throughout the Medicare enrollment process.
